Abstract

The invention relates to a power supply technology for ultrasonic electric spark machining, in particular to a composite pulse power supply for ultrasonic electric spark machining. The composite pulsepower supply for ultrasonic electric spark machining solves the problem that the power supply technology of existing ultrasonic electric spark machining cannot ensure the synchronization between an electric spark discharge pulse frequency and an ultrasonic vibration pulse frequency or lock the phase difference between a spark discharge pulse and an ultrasonic vibration pulse in the ultrasonic electric spark machining process. The composite pulse power supply for ultrasonic electric spark machining comprises a main circuit and a control circuit. The main circuit comprises a spark discharge pulse generating circuit and an ultrasonic vibration pulse generating circuit. The spark discharge pulse generating circuit comprises a first rectifying and filtering module, a first direct current chopping module and a first voltage regulating and discharging module. The ultrasonic vibration pulse generating circuit comprises a second rectifying and filtering module, a second direct current choppingmodule, an inverting module and a second voltage regulating and discharging module. The composite pulse power supply is suitable for ultrasonic electric spark machining.

Description

technical field [0001] The invention relates to a power supply technology for ultrasonic electric discharge machining, in particular to a compound pulse power supply for ultrasonic electric discharge machining. Background technique [0002] With the rapid development of industries such as mold manufacturing, aerospace, and engineering machinery, the demand for high-performance, difficult-to-machine materials such as ceramics, composite materials, and hard alloys and their precision and ultra-precision machining technologies continues to grow. It is a kind of special and precision processing technology, and it is getting more and more people's favor. Under the existing technical conditions, ultrasonic EDM generally uses two sets of power supplies for power supply respectively (one set of power supply supplies power to the discharge gap alone, and the other set of power supply supplies power to the ultrasonic transducer alone). However, this power supply technology is limited...
